A procedure for the assessment of the undrained shear strength profile of soft clays
Thakur, Vikas Kumar Singh; Fauskerud, Odd Arne; Gjelsvik, Vidar; Christensen, Stein Olav; Oset, Frode; Nordal, Steinar; Viklund, Margareta; Strand, Stein-Are (Chapter, 2016)In the geotechnical research community, there is widespread agreement that the choice of the characteristic undrained shear strength (cuA) is very important and plays an essential role in the design and stability analysis ... -
Adaptive isogeometric finite element analysis of steady-state groundwater flow
Bekele, Yared Worku; Kvamsdal, Trond; Kvarving, Arne Morten; Nordal, Steinar (Journal article; Peer reviewed, 2015)Numerical challenges occur in the simulation of groundwater flow problems because of complex boundary conditions, varying material properties, presence of sources or sinks in the flow domain, or a combination of these. In ... -
An Experimental Investigation of Pore Pressure Generation in Moving Debris
Yang, Mingbo (Master thesis, 2016)Debris flow is a typical type of landslide and has huge impact on human life. The moving debris in traditional numerical modeling is assumed as hydrostatic along the flow depth, which is not the actual case when the ... -
An Experimental Study of Anisotropic Stiffness of Tiller-Flotten Quick Clay Using Bender Elements
Morawska, Maja (Master thesis, 2019)Stiffness anisotropy at small strains is a distinctive feature of many natural soils. The nature of the soil is dependent on the geological processes that occur during soil formation. Stress conditions and depositional ... -
Application of a generalized continuous Mohr–Coulomb criterion
Grimstad, Gustav; Rønningen, Jon Abusland; Nordal, Steinar (Chapter, 2018)This paper presents an application of a generalized failure criterion for soils. The presented formulation was originally adopted by the authors to round the corners of the Mohr–Coulomb (MC) yield surface in principals ... -
Arctic Coastal Erosion
Dormoy, Thomas Gerard (Master thesis, 2014)With the recent increase of interest in Arctic, the need rises for new tools for understanding the typical mechanisms of this very unique and so vulnerable area. The coast, which concentrates nearly all of the human ... -
Back Calculation of Measured Settlements for an Instrumented Fill on Soft Clay.
Berre, Stian (Master thesis, 2017)Settlement problems in areas with soft sensitive clays are encountered in many parts of Norway and especially in areas of central Norway. Sampling of sensitive soft soils is challenging and often results in low quality ... -
Backcalculation of Plate Loading Tests using PLAXIS 2D and the Hardening Soil Model
Khanal, Santosh (Master thesis, 2013)Shallow foundations are extensively used to support structures of all sizes in order to safely transmit the structural load to the ground without exceeding the bearing capacity of the ground and causing excessive settlement. ... -
Betydning av spenningsnivå under herding av kalksementstabilisert leire. - Effekter på fasthet og stivhet.
Engeset, Ingrid (Master thesis, 2018)Kalk-/sementstabilisering er en mye brukt metode i Norge for stabilisering av sensitiv leire. Ved å blande inn kalk og sement i leiren økes dens fasthet, og stabilitet og bæreevne forbedres. Forsøk utført på kalksementstabilisert ... -
Bruk av ulike jordmodeller i PLAXIS 2D for modellering av spuntkonstruksjoner i typisk norsk leire
Grendahl, Elin (Master thesis, 2019)Ved dimensjonering av spuntkonstruksjoner for dype utgravinger er det usikkert hvilken jordmodell som best beskriver de faktiske forholdene i jorda. Det er tidligere gjort flere studier av avstivede, dype utgravinger der ... -
Consolidation Settlement of Suction Caissons
Ulvestad, Anders (Master thesis, 2012)Consolidation settlement analysis is an essential part of the design process for suction caissons. However it is a complex task since soil volume important for settlement analyses is directly affected by the installation ... -
Correlation of Properties in Geotechnical Engineering - The impact of Index parameters on Mechanical Properties of Soil
Londalen, Marie Monsen (Master thesis, 2018)In order to effectively use the mechanical parameters of a soil as a tool in soil mechanics, insight about basic properties is necessary. Index properties of soil, such as the water content and the plasticity index influence ... -
Delvis drenert analyse av innvendig avstivet utgraving
Myhrvold, Michael F (Master thesis, 2013)Denne masteroppgaven omhandler analyser av de delvis drenerte effektene som kan oppstå ved innvendig, avstivede utgravinger. Formålet med masteroppgaven er å gjennomføre en numerisk studie av prosessen som styrer den ... -
Detection of Landslides - Using Optical Satellite Remote Sensing
